A) \[300\,\,m\]
B) \[400\,\,m\]
C) \[150\,\,m\]
D) \[75\,\,m\]
Correct Answer: D
Solution :
From equation of motion \[v=u+at\] Given, \[v=20\,\,m/s,\,\,u=10\,\,m/s,\,\,t=5\,\,s\] \[\therefore \] \[a=\frac{10}{5}=2m/{{s}^{2}}\] Also, \[{{v}^{2}}={{u}^{2}}+2a\,\,s\] \[{{(20)}^{2}}={{(10)}^{2}}+2\times 2\,\,s\] \[\Rightarrow \] \[s=\frac{300}{4}=75\,\,m\]You need to login to perform this action.
